Answer:
0.398
Step-by-step explanation:
Answer:
1). x° + 100° + 120° + 100° = 360°
2). x = 40
Step-by-step explanation:
Formula for the sum of the interior angles of a polygon = 
Where n = number of sides of the polygon
From the picture attached,
For n = 4,
Sum of the interior angles of the given polygon = (4 - 2) × 180°
= 360°
Therefore, equation for the sum of interior angles will be,
x° + 100° + 120° + 100° = 360°
x° + 320° = 360°
x° = 360° - 320°
x° = 40°
Answer:
y =-5/4x +11/2
Step-by-step explanation:
First we need to find the slope of the line
4x-5y = 10
Solve for y
Subtract 4x from each side
4x-4x-5y =-4x-10
-5y = -4x-10
Divide by -5
-5y/-5 = -4x/-5 -10/-5
y = 4/5x +2
The slope is 4/5
The slope of a line that is perpendicular is the negative reciprocal
m perpendicular = - (5/4)
We know have a slope = -5/4 and a point (2,3)
We can use the point slope form of a line
y-y1 = m(x-x1)
y-3 = -5/4 (x-2)
Distribute
y-3 =-5/4x +10/4
Add 3 to each side
y-3+3 = -5/4 x +5/2 +3
Get a common denominator
y = -5/4x +5/2 +6/2
y =-5/4x +11/2
Answer:
The answer is 1825.35
Step-by-step explanation:
Since the first week isn’t included, we only count 4 weeks.
So first, 2000 x 0.03 = 60
(By the way 0.03 is 3%)
2000 - 60 = 1940
Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.
Then, week 3:
1940 x 0.03 = 58.2
1940 - 58.2 = 1881.8
Now, the last week, week four:
1881.8 x 0.03 = 56.45
1881.8 - 56.45 = 1825.35.
Therefore, 1825.35 after 5 weeks.
